Title: Heat flow sensor
Inventor: SENDA TAKAO
IPC: H01L35/28
Filed: 1987-07-02
Abstract: PURPOSE:To improve sensitivity and accuracy by using a thermoelectric converting element of a p-type or n-type as a heat flow sensor. CONSTITUTION:The thermoelectric converting element 10 is prepd. by depositing thin films consisting of a good conductor on both faces of the thermoelectric material for the n-type or p-type of a Bi-Te system then cutting the material to a prescribed slice. Metallic pieces 11 are connected to both end faces thereof by using a brazing filler metal 12. The heat flow quantity Q of the sensor formed by connecting the n-type element 10a and the p-type element 10b by the metallic pieces 11 in series is expressed by the equation where the Seebeck coeffts. of the elements 10a, 10b are designated as alphan, deltap, the heat conductivities as kn, kp, the length as l, the sectional area as S, and the generated electromotive force as v. The sensitivity is, therefore, improved by increasing the logarithm and length l of the elements 10a, 10b.

Title: Radiotelephony system
Inventor: MATSUSHITA KOICHI
IPC: H04B7/26
Filed: 1989-06-27
Abstract: PURPOSE:To avoid repetitive call to a slave set whose communication is disabled by sending an end signal to a master set by a slave set when the communication condition is not satisfied and allowing the master set to stop the call to the slave set in response to the reception of the end signal. CONSTITUTION:The master set 1 sends a data including an identification signal of each slave set to plural slave sets 2-4 at calling and the slave sets 2-4 sends the data of each reply in time division based on callout. Then the master set 1 detects the data from the slave sets 2-4 at a detection time interval responding to the number of the slave sets 2-4 to be called. Moreover, the slave sets 2-4 sends an end signal to the master set 1 when the communication condition is not satisfied and in the case of receiving the end signal, the master set 1 eliminates the identification signal of the slave sets 2-4 from the callout data to stop the call of the slave sets 2-4. Thus, the event of continuing a call signal useless to a slave set disabled of communication is prevented.

Abstract: PURPOSE: To improve the protection ability to high frequency of surge voltage by inserting a C-B junction diode and a B-E junction diode in parallel between a signal terminal and a first power terminal. CONSTITUTION: A junction diode 3a between a collector and a base slow in response and a junction diode 10 between an emitter and a base quick in response are connected in parallel between a signal terminal and a positive power source. When positive surge voltage is applied, low-frequency components large in power leave off to high potential power wiring 8, with forward currents flowing to both of the protective diodes 3a and 10, and high-frequency components small in power leave off to the high-potential power wiring 8, with forward currents flowing to the protective diode 10. Therefore, the transistor of the inner circuit gets to hard to be broken by high-frequency to low-frequency surge voltage, and the electrostatic breakdown strength of a semiconductor integrated circuit can be raised, without using special manufacture process.
